Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Missouri has no statewide residential building/mechanical code, so permit and inspection requirements are set locally by each city or county.

The 25C tax credit (30% up to $2,000 for heat pumps, $600 for high-efficiency AC) can lower out-of-pocket costs.
